摘要
由于支护高度低,立柱伸缩比大,空间布局狭小,液压系统布置困难,薄煤层支架设计受到制约。针对以上问题,以ZY4000/07/15D薄煤层液压支架设计为实例,从总体设计、立柱及千斤顶、液压系统方面进行了优化设计。仿真结果及投入使用情况均表明,优化后的薄煤层液压支架各方面均能满足使用要求。
Due to the low height of support,large contraction ratio of leg, and small space of support layout,the layout of hydraulic system is difficult,the design of hydraulic support in thin coal seam was constrained. Aiming at the above problems,taking the design of hydraulic support ZY4000/07/15D in thin coal seam as an example,optimization design was carried out in the following aspects,such as the integrated design,the leg and the jack,the hydraulic system. Results of simulation and practice show that,optimized hydraulic support can meet the requirements the field application.
